Installation

graphstruc can be built using either the Fortran Package Manager (fpm) or CMake.

Requirements

Compiler: GCC gfortran 14.1.0 or later
Build tool: fpm or CMake 3.17.5+
Dependencies: coreutils (fetched automatically)

Using fpm (Recommended)

The simplest way to use graphstruc is as a dependency in your fpm project.

As a Dependency

Add to your project’s fpm.toml:

[dependencies]
graphstruc = { git = "https://github.com/nedtaylor/graphstruc.git" }

Then use in your code:

use graphstruc, only: graph_type

fpm will automatically fetch and build graphstruc and its dependencies.

Direct Installation

To build graphstruc directly:

git clone https://github.com/nedtaylor/graphstruc.git
cd graphstruc
fpm build

Run the test suite:

fpm test

Run the example programme:

fpm run --example

Using CMake

For projects using CMake:

git clone https://github.com/nedtaylor/graphstruc.git
cd graphstruc
mkdir build && cd build
cmake ..
make

Run tests:

make test

Verifying Installation

Test your installation with this simple programme:

program test
  use graphstruc, only: graph_type
  implicit none

  type(graph_type) :: g

  call g%add_vertex(feature=[1.0])
  write(*,*) 'Success! Vertices:', g%num_vertices
  call g%clear()
end program

Compile and run:

fpm run test
